Powerflex-6250 Six Channel Amplifier
The power amplifier shall be a multichannel unit consisting of six
independent channels. Each amplifier shall be able to deliver 150
watts into 8 ohms, or 250 watts into 4 ohms. In addition, bridged
pairs shall be able to output 500 watts each into 8 ohms. Also,
when pairs are bridged, the unit shall provide 500 watts capable
of driving a 70 volt system without the use of external trans-
formers.

of driving a 70 volt system without the use of external trans-
formers.
The amplifier shall have a gain of 30.1dB and an input sensitivity
of 1.05 Volts RMS for full rated output. Frequency response shall
be 20Hz to 20kHz +/- 0.5dB at 8 ohms. The unit shall be stable
into any load, including pure capacitors and inductors. Hum and
noise shall be at least 100dB below full output (A-weighted) and
SMPTE intermodulation distortion shall be less than 0.2%. Total
Harmonic Distortion (20Hz - 20KHz at 8 ohms) shall be less than
0.2%.
Each amplifier channel shall be supplied with an input attenuator
located on the rear panel input module. Each pair of inputs shall
have a bypassable high pass filter of 12dB/octave at 50Hz, a
switch to select stereo or mono mode and a switch to select dual
or bridge mode. There shall be an input ground switch located on
of 1.05 Volts RMS for full rated output. Frequency response shall
be 20Hz to 20kHz +/- 0.5dB at 8 ohms. The unit shall be stable

the input module to select chassis or floating ground operation.
The inputs shall be active balanced design, with an impedance of
10K ohm accessible with combination XLR - 1/4” jacks and euro-
bloc connectors. The outputs shall be terminated with a 5-way
binding post connector.

The unit shall be capable of operation by means of its own built-
in power supply connected to 110 - 125V AC, 220 - 250V AC, 50/
60Hz. Dimensions of the unit shall be 19”L X 5.25”H X 16.5”D.
The chassis shall be constructed from steel with an aluminum
face panel and weigh 45lbs.
